I use VSCode, not the Arduino IDE. I saw and tried to use a lot of code snippets which are provided for Arduino projects...

So when I copy/paste these examples into my VSCode and try to compile it fails. (I won't believe that people offer non-working examples.)

When I place the functions above the function calls it compiles.

Is this normal behavior or do I have to add some settings to get this working as provided?

Fails:

myfunction(); void myfunction(){ return 0; } 

Works:

void myfunction(){ return 0; } myfunction();

Fails in VSCode (works in Arduino IDE):

#include "Arduino.h" void setup() { } int zero = 0; void loop() { zero = myfunction(); } int myfunction(){ return 0; } 

Works in VSCode (Works in Arduino IDE):

#include "Arduino.h" void setup() { } int zero = 0; int myfunction(){ return 0; } void loop() { zero = myfunction(); }
